Convergence of 60 GHz Radio Over Fiber and WDM-PON Using Parallel Phase Modulation With a Single Mach–Zehnder Modulator

We propose a converged radio over fiber and wavelength division multiplexing passive optical networks (WDM-PON) system compatible with wired and 60 GHz band wireless transmission by implementing two-band modulation with a single Mach-Zehnder modulator as parallel phase modulators. In this paper, broadband millimeter wave generation, which is compliant with the ECMA 387 standard, and 2.5 Gbps baseband transmission, which feeds up the requirement of fiber-to-the-home, are simultaneously realized after 25 km long optical fiber transmission. Furthermore, the interference between RF and baseband modulations is theoretically and experimentally investigated. The RF modulation impacts to the baseband signal for different RF modulation formats are deeply investigated.
